Everything megamaster does, and why it does it that way

Each page below covers one feature end to end — what it's for, how to read it, and the design decisions behind it. Start with Getting Started if you're new; jump straight to a feature page if you already have hands imported.

01

Getting started

Import your first hand history export and see it land in the app.

02

Notation glossary

The compact line notation used everywhere in the app — X, F, C, B<size>, and how streets join.

03

Lines

Fix a matchup, read the whole postflop tree, then drill into any single decision.

04

Decision-node explorer

Walk any line, on any street, one decision at a time — with a real range bar at every hero node.

05

Lines map

Every node you have a baseline for, swept at once and ranked by how much money the difference touches.

06

Population reports

Define a group of opponents by how they play, then see how that group plays a specific spot.

07

Results & sessions

Sessions computed from real time gaps, a cumulative graph, and a per-hand drill-down.

08

The replayer

A real visual table — pot and stacks tracked live as you step through a hand.

09

Solving hands

One click sets up and solves a real hand's exact spot in your own local PioSolver.

10

Rules & texture buckets

Author your own strategy rules, keyed to board textures you define.

11

Tags

Turn a leak you found into a reviewable list of the actual hands behind it.

12

The low-memory engine

Halves the memory a solve needs so bigger trees fit — what that costs, and the two things it refuses to do rather than get wrong.

13

Trainer score

EV loss, action mix and range balance, per street — one number that never lets a leak hide another.

14

Sizing configs

Pick the bet sizes you practice, and see what each simplification costs against the full solve.

15

Routines & puzzles

Day plans of drills ordered by your leaks, difficulty modes, and range-ranking puzzles.

16

Solver accuracy

The accuracy targets behind every baseline and priced rule, and how to read a package's convergence.
